Is poker a game of skill or chance? This question has been discussed and

argued in many places and is the center of the arguments for and against

legalizing Texas holdem and other forms of poker in many places, including

online.

We have created a poker math and probability PDF chart (link opens in a new window) which lists a variety of probabilities and odds for many of the common events in Texas hold ‘em. This chart includes the two tables above in addition to various starting hand probabilities and common pre-flop match-ups.

Texas Hold'em Poker probabilities When calculating probabilities for a card game such as Texas Hold'em, there are two basic approaches. The first approach is to determine the number of outcomes that satisfy the condition being evaluated and divide this by the total number of possible outcomes. Trashy – Hands like Q5o, J6o, 52o and 84o are among the weakest starting hands in Texas Hold’em and should never be played as a raise first in. The majority of Texas Hold’em starting hands are in this category, so it’s important to get into the habit of only selecting appropriate hands.

The answer to this question boils down to the mathematics behind the game. If

the math shows one player can win more often than another based on the

mathematical and statistical truths about Texas holdem then the game is one of

skill.

Let’s look at a few facts before moving on.

- Fact 1
Texas holdem is played with a deck of 52 playing cards, consisting of

the same four suits, and 13 ranks in every deck. You know each deck has an

ace of spades, and ace of hearts, an ace of clubs, and an ace of diamonds.

The same is true for kings, queens, and all of the ranks down through twos. - Fact 2
Over a long period of time each player will play from each position at

the table an equal number of times. In other words, each player will play in

the small blind, the big blind, under the gun, on the button, etc. an equal

number of times as other players. If you take two individual players it

might not be 100% the same, but it’ll be close. When you take thousands of

players and average their times played in each position mathematically they

each play the different positions an equal number of times. - Fact 3
The rules in each game are the same for every player at the table.

- Fact 4
The player that starts the hand with a better two card starting hand

wins the hand more often than the player with a worse hand. This has been

proven by computer simulations that run millions of hands and consider every

possible outcome.

## Why Is This Important?

The reason all of this is important to Texas holdem players is that you can

use all of this math to help you win.

Though there are thousands of possibilities on every hand of Texas holdem,

you can use the fact that everything is based on a set of 52 cards to predict

outcomes and possibilities at every stage for every hand.

If you start the hand with two aces as your hole cards, you know that the

remaining 50 cards in the deck only have two aces. The remaining 48 cards

consist of four of each rank below the aces. At the beginning of the hand you

don’t know where any of the other cards are located, but as the hand progresses

you learn where some of them are located.

Continuing with the example, if the flop has an ace and two fours, you hold a

full house. You also know the only hand at this time that can beat you is four

fours. Because two fours are on the flop, the number of times a single opponent

has the other two fours is 1 in 1,326 hands. This is such a small percentage of

the time that you always play the full house in this example as if it’s the best

hand.

How do we know the number of times the opponent has the other two fours?

Because two fours are on the flop, let’s say the four of hearts and the four

of diamonds, so you know that your opponent has to have the four of clubs and

the four of spades. The chances of the first card in their hand being one of

these two cards are two out of 52. If they get one of them as the first card

that leaves the single other card they need out of 51 unseen cards, or one out

of 51.

You multiply two over 52 times one over 51 and this gives us the 1 out of

1,326 hands.

## Basic Texas Holdem Math

Some of the math we discuss on this page can be complicated and the truth is

some players won’t be able to use it all. But that doesn’t mean they can’t be

winning Texas holdem players. The math covered in this section forms the

building blocks for the advanced math covered lower on the page.

Every Texas holdem player can use the basic math included in this section,

and if you aren’t using it yet you need to start right away.

### Starting Hands

At the most basic level of Texas holdem everything starts with your starting

hand. As we mentioned above, mathematically the player who stars the hand with

the better starting hand wins more than the player with the inferior hand.

This means the first math lesson you need to learn and start using is to play

better starting hand on average than your opponents. While this can get

complicated, especially in games with many multi way pots, you still need to

learn how to play better starting hands.

If you take nothing else from this page, if you simply tighten up your

starting hand selection it’ll immediately improve your results.

### Position

It’s difficult to directly relate position to mathematics, but the main thin

to know is the later your position, the better your chances to play in a

positive expectation situation. We’ll discuss expectation in a later section,

but it’s important to understand that having position on an opponent is a strong

advantage that equates to a mathematical advantage over the long run.

### Outs

One of the most important skills Texas holdem players need to develop is the

ability to determine the number of outs, or cards remaining in the deck that can

complete the hand they’re drawing to. You use this information to determine your

chances of winning the hand as well as to determine the pot odds. Pot odds are

discussed in the next section, but they show you whether or not a call is

profitable in the long run when an opponent makes a bet.

We can determine how many outs you have because we know what’s in the deck

and what we need to improve our hand. If you have a king, queen, jack, and 10

after the turn you know any of the four aces or four nines complete your

straight.

This means you have eight outs. You’ve seen six cards, so the deck has 46

cards remaining in it. Don’t make the mistake of thinking about the cards that

have been folded or your opponent holds. You haven’t seen these cards so any

unseen card is still considered a possible river card.

In other words, on average, if you play this situation 46 times you’re going

to complete your straight eight times and not complete it 38 times.

You should always consider how many outs you have in every situation while

playing. B knowing your outs you have another piece of information that can help

you make profitable decisions throughout the hand.

### Pot Odds

The next question many players ask after they learn how to determine their

out sis how they can use this information to make more money at the table. This

is where pot odds come into play.

Pot odds are simply a ratio or comparison between the money in the pot and

the chances you have of completing your hand. You use this ratio to determine if

a call or fold is the best play based on the information you currently have.

If you consider the example in the last section concerning the straight draw,

you know that the deck holds eight cards that complete your straight and 38

cards that don’t. This creates a ratio of 38 to 8, which reduces to 4.75 to 1.

You reduce by dividing 38 by 8.

The way you use this ratio is by comparing it to the amount of money in the

pot and how much you have to put into the pot. If the pot odds are in your favor

it’s profitable to call and if not you should fold.

If the pot has $100 in it and you have to make a $10 call the pot is offering

10 to 1 odds. You determine this the same way as above, by dividing $100 by $10.

If you’re in the situation described above of drawing to a straight on the

river you can see that a call is correct because the pot is offering 10 to 1 and

you have a 4.75 to 1 chance of winning.

## Texas Hold'em Poker Hands In Order

On the other hand of the pot has $100 in it and you have to put $40 in to see

the river the pot is only offering 2.5 to 1 odds and your chances of hitting

your straight are still 4.75 to 1 so you should fold.

Pot odds can get complicated, especially when you start considering how they

work when you’re determining the correct play with both the turn and river to

come.

Fortunately charts are available to quickly check the odds of hitting your

hand based on how many outs you have. We’ve included one next so all you have to

do is determine your outs and compute the odds the pot is offering. Then compare

the two to see if it’s profitable to call or fold.

Number of Outs | Turn & River Combined | River Only |
---|---|---|

1 | 22.26 to 1 | 45 to 1 |

2 | 10.9 to 1 | 22 to 1 |

3 | 7 to 1 | 14.33 to 1 |

4 | 5.06 to 1 | 10.5 to 1 |

5 | 3.93 to 1 | 8.2 to 1 |

6 | 3.15 to 1 | 6.67 to 1 |

7 | 2.6 to 1 | 5.57 to 1 |

8 | 2.17 to 1 | 4.75 to 1 |

9 | 1.86 to 1 | 4.11 to 1 |

10 | 1.6 to 1 | 3.6 to 1 |

11 | 1.4 to 1 | 3.18 to 1 |

12 | 1.22 to 1 | 2.83 to 1 |

13 | 1.08 to 1 | 2.54 to 1 |

14 | 0.95 to 1 | 2.29 to 1 |

15 | 0.85 to 1 | 2.07 to 1 |

16 | 0.75 to 1 | 1.88 to 1 |

17 | 0.67 to 1 | 1.71 to 1 |

18 | 0.6 to 1 | 1.56 to 1 |

19 | 0.54 to 1 | 1.42 to 1 |

20 | 0.48 to 1 | 1.3 to 1 |

When you’re determining your pot odds for the turn and river you determine

them on the turn and then if you don’t hit your draw you determine them again on

the river. This often happens, especially in limit Texas holdem. But if an

opponent moves all in on the turn you simply use the turn and river combined

odds in your decision.

## Advanced Texas Holdem Math

Many beginning Texas holdem players look at a discussion about expectation

and instantly decide it’s too hard and ignore it. When they do this they

severely hurt their long term chances at being a profitable player.

We’ve broken down how to look at situations while playing poker in a simple

manner that almost any player can use below. Do yourself a favor and go into

this with an open mind. Once you understand it at a simple level you can learn

more as you gain experience. You may be surprised at just how easy it gets to

determine positive and negative expectation with a little practice.

### Expectation

Expectation is what the average outcome will be if you play the same

situation hundreds or thousands of times. Once you determine the expectation you

know if a situation offers positive or negative results on average.

Your goal as a Texas holdem player is to play in as many positive expectation

situations as possible and avoid as many negative expectation situations as

possible.

You need to understand that expectation is something that can be applied to

almost any situation in poker, but it’s also subjective in many areas.

- If you play at a table where every opponent is better than you in the long

run you’re going to lose money. This is a negative expectation situation. - If you play at a table where every opponent is a worse

player than you it’s a positive expectation situation because you’re going to

win in the long run.

The problem is determining whether a situation is positive or negative

expectation when you sit down at a table with some players who are better than

you and some who are worse.

You can find many situations where it’s easier to determine expectation

mathematically, and we’ll teach you how to do this now. While this may seem

overly complicated at first, especially to do at the table while playing, you

don’t need to know exactly how negative or positive a situation is, you only

need to know if it’s positive or negative.

Once you determine if a situation is positive expectation or negative

expectation you simply remember the next time you’re in a similar situation.

Once you start determining expectation you’ll find that you learn mist

situations quickly and only have to think through an occasional situation at the

table.

## Texas Holdem Probability Calculator

The best way to see how to determine expectation is by running through a

couple examples.

### Example 1

You’re facing a bet after the turn and you have four to a flush.

The pot had $400 in it and your opponent bet $100. You’re certain that if you

miss your flush draw you’ll lose and when you hit your flush draw you’ll win.

In order to see the river you have to call the $100 bet. When you lose you

lose $100, and when you win you get back $600. You get your $100 back plus the

$400 that was in the pot plus the $100 bet your opponent made.

Many players claim that part of the money already in the pot is theirs, but

once you put money into the pot it isn’t yours. The only way to get it back is

to win the pot. So you can’t consider it in any other way when determining

expectation.

The way to see if it’s positive or negative to call is to determine what will

happen on average if you play the same situation many times. Most players find

it easiest to determine by pretending to play the hand 100 times.

In this example you’re going to hit your flush 9 out of 46 times. This means

19.56% of the time you’re going to win and 80.44% of the time you’re going to

lose. To make this simple we’ll round these numbers off to 20% and 80%.

If you have to put $100 in the pot 100 times your total investment is

$10,000. The 80 times you lose you get nothing back. The 20 times you win you

get $600. 20 times $600 is $12,000. When you take the $12,000 you win and

subtract the $10,000 you lose when you play the situation 100 times, you see

that you win $2,000 overall.

To determine how much you win on average per hand simply divide the $2,000 by

100 to get a positive expectation of $20 per hand. This means that every time

you’re in this situation you’ll win on average $20.

The truth is you may win a little more because we’re ignoring the river.

Because you know you can’t win if you miss your flush, you always need to fold on

the river when you miss your draw. Every once in a while you may be able to

extract a small bet from your opponent on the river when you hit your flush,

increasing your average expectation. Sometimes it’s even correct for your

opponent to call on the river in this situation. See the next example to see

why.

### Example 2

Let’s say you’re playing the same hand as above but you have a

straight and your opponent appears to be drawing to a flush. You’re on the

river, the pot has $600 in it, and the board has the third suited card hit on the

river.

If your opponent was drawing to the flush, they completed it and you’re going

to lose the hand. In this situation your opponent bets $20.

In this situation you clearly have to call.

The reason you have to call is because you can’t know for certain your

opponent was drawing to the flush. They may be bluffing or have two pair or any

other number of hands that aren’t as good as your straight.

Let’s look at the math behind this decision.

If you play the situation 100 times your total investment is $20 times 100,

or $2,000.

When you win you get $640, consisting of the original $600 pot, your

opponent’s $20 bet, and your $20 call. If you win three hands you get back

$1,920 for a loss of $80, or 80 cents per hand.

If you win at least four times you’re in a positive expectation situation.

Four wins nets $2,560 for an overall win of $560, or $5.60 per hand.

What this means is if your opponent is bluffing or has a weaker hand just

four times out of 100 or more, calling is a positive expectation situation. Four

times out of 100 is only 4%. You’ll win at least 4% of the time in this

situation.

The numbers get closer the more your opponent bets on the river, and the

closer the numbers get the more you’re going to need to use what you know about

your opponent to determine if a situation is positive or not.

**Start looking at every decision you make at the Texas holdem tables in termsof positive and negative expectation.It’s hard at first, but the more youpractice the better you’ll get at predicting if a situation offers positiveexpectation.**
